System for preventing fall and suicide

ABSTRACT

The present disclosure relates to a falling and death leap defense rotating cylinder system, including a supporter; a rotator that is rotatably installed in the supporter, and that inhibits a death leap of a death leap attempter by rotating when grasped by the death leap attempter; and a spiked unit that forms a cutting edge, and that is detachably installed in any one or more of the supporter and the rotator. According to the present disclosure, by the spiked unit detachably installed in the supporter or the rotator, a falling and death leap of a death leap attempter may be inhibited more effectively.

TECHNICAL FIELD

The present invention relates to a falling and death leap defenserotating cylinder system, and more particularly, to a falling and deathleap defense rotating cylinder system that is capable of inhibiting afalling and death leap of a death leap attempter more effectively byusing a spiked unit installed detachably in a supporter or a rotator.

BACKGROUND OF THE INVENTION

South Korea's suicidal death rate in 2011 was 31.7 persons perpopulation of 100 thousand, marking the highest among OECD countriessince 2003. Even though the government put forth suicide preventioncomprehensive measures twice in each of 2004 and 2009, the suicidalrates are still increasing.

Meanwhile, in recent days, especially, suicidal rates of falling frombridges, high-rise buildings and the like are rapidly increasing.Facilities for preventing such suicidal falls include fences installedon the edges of bridges, high-rise buildings and like.

Fences installed as bridge rails constructed along rivers or the sea areinstalled in a relatively low height of within 1 m in consideration ofwind load applied to the bridges and harmony with the surroundingscenery or design and how they look from a distance and the like. Asaforementioned, since such conventional fences are installed in lowheights, they are not effective in preventing a death leap attempterfrom climbing the fences and deliberately making a death leap.

Meanwhile, fences for rooftops of large buildings must be installed in aheight of 2 to 3 m so as to prevent any falls. However, in most cases,fences are being installed in heights of 1 to a little over 1.2 m forcost and aesthetic reasons, and thus fences installed in buildingscannot effectively prevent deliberate death leaps just like in bridges.

Korean Registered Patent no. 10-1631813 discloses a Death Leap DefenseRotating Cylinder System.

The Death Leap Defense Rotating Cylinder System of Korean RegisteredPatent no. 10-1631813 includes a supporter installed in a structure anda rotator rotatably installed in the supporter and that rotates, whereinthe system inhibits a death leap attempt of a death leap attempter usingrotation of the rotator as the death leap attempter grasps the rotator.

According to the Death Leap Defense Rotating Cylinder System of KoreanRegistered Patent no. 10-1631813, the position of the supporter isfixated. Therefore, there is a problem where, if the death leapattempter inhibits the rotation of the rotator using other tools anddevices etc., and then climbs while grasping the rotator and supporter,chances of a successful death leap becomes very high.

SUMMARY

As illustrated in FIGS. 1 to 18, the falling and death leap defenserotating cylinder system according to the first embodiment of thepresent disclosure 100 includes the supporter 110, the rotator 120, asurveillance camera 130, a speaker 140, a control center 150 and thespiked unit 160.

The supporter 110 is installed on a ground or a structure, and therotator 120 that will be explained hereinafter is to be installed on thesupporter 110.

Here, the ground may be a floor surface where the supporter 110 is to beinstalled, that is, the floor surface of an apartment, high-risebuilding, facility at an edge of a roof of a general housing building orbridge, freeway, overhead walkway, ship and the like.

Further, here, the structure may be an apartment, high-rise building,facility at an edge of a roof of a general housing building or bridge,freeway, overhead walkway, existing rails or theater installed on bothedges of a ship, tourist side, rails installed in a playground, objectssuch as H beam installed in other places with high risk of fall and thelike.

That is, the supporter 110 may be installed solely on the ground usingan anchor (refer to FIG. 17), installed on the ground in an earth workmethod, installed on an upper end of an H beam installed on the ground(refer to FIG. 17), or installed on existing rails.

In the case where the supporter 110 is installed on existing rails, ininstalling a death leap defense system, the inconvenience of removingthe entirety of the existing rails is reduced, and when constructing thedeath leap defense system, the existing rails can be utilized as thereare, and thus there is an advantage of shortening the constructionperiod and saving the construction costs, and also an advantage of easyrepair and maintenance.

Such a supporter 110 changes posture such that the center of gravity ofthe death leap attempter is disturbed when external force is applied asthe death leap attempter grasps the rotator 120 that will be explainedhereinafter. One end of the supporter 110 is installed in the structure,while on the other end of the supporter 110, the rotator 120 that willbe explained hereinafter may be installed such that it is rotatable.

The supporter 110 may be manufactured in a casting method. The supporter110 may be manufactured in various lengths depending on the sitesituations. However, when the supporter 110 is long, there is a problemwhere the supporter 100 may be distorted. Therefore, the supporter 110may have a protruding wing at one side surface to prevent theaforementioned problem of distortion.

Meanwhile, more specifically, the supporter 110 includes the combiningunit 111 and the main body 112.

The combining unit 111 is combined with the ground or the structure, andthe main body 112 that will be explained hereinafter is installed on anupper surface of the combining unit 111. Such a combining unit 111 maybe combined with the structure by a locking member.

Meanwhile, in the case where the combining unit 111 is being combinedwith the structure in a method such as bolting combination and the like(combination in the form of damaging the structure itself), there occursa problem regarding the safety rating of the existing structure.Therefore, in the case where the combining unit 111 is being combinedwith the structure, it is desirable that the combining unit 111 iscombined with the structure as it suppresses an outer surface of thestructure, as illustrated in FIG. 18. (This does not affect the ratingof the structure).

The main body 112 is where the rotator 120 that will be explainedhereinafter is to be installed on one end of the main body 112, and theother end of the main body 112 is installed on an upper surface of thecombining unit 111 mentioned above. Such a main body 112 is formed in anarrower wide than the combining unit 111. That is, the main body 112 isinstalled on the upper surface of the combining unit 111 in a directionperpendicular to the direction in which the combining unit 111 isinstalled in the structure. Here, the width of the main body 112 isformed to be narrower than the width of the combining unit 111.

According to the combining structure of the main body 112, less materialis input when manufacturing the main body 112, and thus there is aneffect of saving the manufacturing cost of the main body 112.

Meanwhile, the main body 112 may be provided to have a predeterminedangle x against the ground. It is desirable that the predetermined anglex is provided to be between 40 and 75 degrees, which includes both acuteand obtuse angles against the ground. That is, in the case where thepredetermined angle x is an acute angle, the main body 111 tilts towardsthe death leap attempter, and in the case where the predetermined anglex is an obtuse angle, the main body 111 tilts away from the death leapattempter (refer to FIGS. 3 and 6).

Further, such a main body 112 may be manufactured in various forms thatsuit the surrounding environment in consideration of the surroundingenvironment (refer to FIG. 7).

Further, on such a main body 112, a projection 112 d may be formed. Dueto such a projection 112 d, the death leap attempter can be effectivelyprevented from trying to grasp the supporter 110 and climbing over.

Further, on one side surface of the main body 112, an installationgroove may be formed along a longitudinal direction. And on such aninstallation groove, the spiked unit 160 that will be explainedhereinafter may be detachably installed in a sliding method.

According to the aforementioned spiked unit 160, the death leapattempter is prevented from grasping the main body 112 in the firstplace, and thus the death leap attempt of the death leap attempter canbe inhibited more effectively.

Meanwhile, as illustrated in FIGS. 4 and 5, on the main body 112, anelastic means (not illustrated) may be installed for allowing an upperend of the main body 112 to tilt towards the ground when a predeterminedexternal force is applied to the upper end of the main body 112 and forrestoring the upper end of the main body 112 when the external force isremoved. According to such an elastic means (not illustrated), in thecase where the death leap attempter grasps a pipe 121 installed on theupper end of the main body 111, the pipe 121 tilts towards the ground,thereby disturbing the center of gravity of the death leap attempter.Therefore, according to such an elastic means (not illustrated), thedeath leap attempt of the death leap attempter can be inhibited moreeffectively.

The rotator 120 is rotatably installed on one end of the main body 112mentioned above. When grasped by the death leap attempter, the rotator120 rotates and inhibits the death leap of the death leap attempter.

Such a rotator 120 may be provided in plural, and may be slantlyinstalled on the main body 112 sequentially. Here, it is desirable thatthe distance between the rotators 120 is provided to be smaller than thenarrowest width of a normal adult's head (13 cm to 15 cm), so that thedeath leap attempter cannot go through. Meanwhile, supposing a normaladult's height is 170 cm, considering the aforementioned distance of therotators 120, it is desirable that three rotators 120 are provided andarranged sequentially.

The aforementioned rotator 120 includes a pipe 121, an axis 122, abearing 123 and a pressure sensor 124.

The pipe 121 forms inner space where the axis 122 and bearing 123 thatwill be explained hereinafter are to be installed. When grasped by thedeath leap attempter, the pipe 121 contacts the bearing 123 inside androtates, thereby easily preventing the death leap attempter fromgrasping the pipe 121 and climbing over.

It is desirable that such a pipe 121 is provided in a greater diameterthan a normal person's hand span so that it cannot be easily grasped bythe death leap attempter.

Further, it is desirable that such a pipe 121 is made of aluminum sothat it has reduced weight but increased strength.

Meanwhile, on such a pipe 121, the pressure sensor 124 may be installed,and near the pipe 121, facilities such as a surveillance camera 130 anda speaker 140 that will be explained hereinafter may be installed. Bythe facilities such as the pressure sensor 124, the surveillance camera130 and the speaker 140, when the death leap attempter grasps the pipe121, the control center 150 may perceive this immediately, and generatealarm sounds with the speaker 140 and input management manpowerinstantly at the same time. By doing this, death leaps of death leapattempters can be inhibited more effectively.

Further, as illustrated in FIG. 7, on an outer circumference of such apipe 121, a plurality of blades 121 a may be installed along alongitudinal direction of the pipe 121. The blades 121 a may make itmore difficult for the death leap attempter to grasp the pipe 121,thereby inhibiting the death leap attempt of the death leap attemptermore effectively.

Meanwhile, as illustrated in the expanded portion in FIG. 7, such blades121 a may be bent at an end side while having an inclination against adirection perpendicular to a tangent line of the outer circumference ofthe pipe 121. Due to such shapes of the blades 121 a, it is practicallyimpossible for the death leap attempter to grasp the pipe 121, and thusthe death leap attempt of the death leap attempter can be inhibited moreeffectively.

In the case where such blades 121 a are installed in the pipe 121, thepipe 121 must be provided in a smaller diameter than the diameter of thepipe 121 when the blades 121 a are not installed, in which case there isan effect of significantly saving the manufacturing cost of the pipe121.

Further, when such blades 121 a are installed in the pipe 121, the pipe121 may be rotated by wind. If an electric charge module is connected tothe pipe 121 that rotates by the aforementioned process, an effect ofproducing electricity may also be expected.

Further, in such a pipe 121, a brake means (not illustrated) forinhibiting rotation of the pipe 121 may be additionally installed. Sucha brake means (not illustrated) is installed to be interlocked to aproximity sensor (not illustrated) that senses presence of an objectnear the pipe 121. Therefore, if there is no death leap attempter nearthe pipe 121, the brake means (not illustrated) operates and thus thepipe 121 does not rotate, but when a death leap attempter approachesnear the pipe 121, the proximity sensor (not illustrated) may sense thisand release the brake means (not illustrated), thereby rotating the pipe121. According to the aforementioned process, the pipe 121 being rotatedby the effects of the wind is effectively prevented, and thus theproblem where the pipe 121 is rotated by the wind to generate noise iseffectively prevented.

Further, in the pipe 121, an installation groove may be formed along thelongitudinal direction. And in such an installation groove, the spikedunit 160 that will be explained hereinafter may be detachably installedin a sliding method.

Due to the aforementioned spiked unit 160, the death leap attempter isprevented from grasping the pipe 121 in the first place, and thus thedeath leap attempt of the death leap attempter can be effectivelyinhibited.

Further, the pipe 121 may be made of polycarbonate and that its insideis transparent. If a lighting (not illustrated) is installed inside sucha transparent pipe 121, there is an aesthetic effect and an effect ofbeing utilized as traffic inducement etc. Further, when using thetransparent pipe 121, there is an effect of displaying a phrase, photo,image, hologram and the like for preventing death leap attempts insidethe pipe 121, thereby delivering a message that is helpful to death leapattempters.

The axis 122 is installed at one end of the main body 112, and arrangedin the inner space mentioned above and thus connected to the bearing 123installed in the inner space. Such an axis 122 may be formed such thatits diameter increases along the direction towards the one end of themain body 112 in the bearing, and thus when seen from the side surface,provided in a taper form (that is, a shape where an upper side ishorizontal and a lower side has an inclination).

Due to such a shape of the axis 122, fluid being introduced from outsideto an upper side surface of the axis 122 can easily flow towards themain body 112 along an inclined plane at a lower side of the axis.(Meanwhile, when the axis 122 is rotated by external force and then theexternal force is removed, by the self-weight of the lower side portionof the axis 122, the axis 122 is naturally rearranged in the form wherethe upper side is horizontal and the lower side has an inclination).

Due to such a shape of the axis 122, when a substance from outside, suchas rain, moisture and snow gets into the inner space along the axis 122,by changes in the diameter of the axis 122, that is by the inclinedplane of the axis 122, the substance from outside cannot get into theinner space, but can easily escape outside again along the inclinedplane. Accordingly, a phenomenon where the bearing 123 freezes at winterand thus keeping the pipe 121 from rotating is effectively prevented.

The bearing 123 is connected to the axis 122 such that it is rotatablein the inner space, and contacts the inner circumference of the pipe 121mentioned above. Due to such a bearing 123, when the death leapattempter grasps an outer surface of the pipe 121, the pipe 121 can beeasily rotated.

Such a bearing 123 is arranged in the inner space. That is, the bearing123 is installed inside the pipe 121 without being exposed outside, andthus there is a low chance that it can be frozen by the substance fromoutside such as rain, moisture and snow. Accordingly, a phenomenon wherethe pipe 121 is not rotated at winter is effectively prevented.

In such a bearing 123, there may be installed a plurality of auxiliaryaxes 123 a on its outer surface such that when the pipe 121 rotates, thepipe 121 faces only towards the road, and a stumbling member 123 b thatis made of an elastic material and that is installed in one or more ofthe plurality of auxiliary axes 123 a.

As illustrated in FIG. 10, when the bearing 123 is rotated in acounterclockwise direction, the stumbling member 123 b is rotated as itis since it is not interrupted by the shape formed inside the bearing123. However, as illustrated in FIG. 11, when the bearing 123 is rotatedin a clockwise direction, the stumbling member 123 b gets stuck due tothe interruption by the shape formed inside the bearing 123, andaccordingly, rotation of the pipe 121 is inhibited.

In the case where the bearing 123 rotates the pipe 121 in only onedirection as mentioned above, when the death leap attempter grasps thepipe 121, the pipe 121 is rotated towards the inside, that is towardsthe death leap attempter, and thus the death leap and falling of thedeath leap attempter can be effectively prevented. Further, for example,there may be a case where a worker steps on the pipe 121 with his/herfoot while working near the pipe 121 using a ladder and the like. Inthis case, the pipe 121 will be rotated towards the inside, and thus theworker may fall towards the road. Therefore, due to such a bearing 123,safety of the worker can be guaranteed effectively.

The pressure sensor 124 is installed in the bearing 123, and senses thedeath leap attempter contacting the bearing 123 and generates contactinformation, and then delivers the generated contact information to thecontrol center 150. Meanwhile, it is desirable that such a pressuresensor 124 is installed in the inner space of the pipe 121 mentionedabove so that it is prevented from being damaged by outside dust, rainand the like.

Due to the rotator 120 including such a pipe 121, axis 122, bearing 123and pressure sensor 124, when the rotator 120 is grasped by the deathleap attempter, the rotator 120 can rotate and the death leap of thedeath leap attempter can be inhibited effectively.

The surveillance camera 130 is installed in the structure side andphotographs the death leap attempter and generates image information.The surveillance camera 130 is electrically connected to the controlcenter 150 that will be explained hereinafter to transmit the generatedimage information to the control center 150. Due to such a surveillancecamera 130, when the death leap attempter attempts the death leap, thecontrol center 150 may sense the attempt immediately, and thereby inputmanagement manpower to the death leap attempter instantly.

The speaker 140 is installed in the structure side and generates alarmsounds. The speaker 140 is electrically connected to the control center150 and is controlled by the control center 150. Due to such a speaker140, it is possible to easily inhibit the death leap of the death leapattempter.

The control center 150 monitors the death leap attempter based on theinformation photographed in the surveillance camera 130. When thepressure sensor senses that external force is applied to the pipe 121,the control center 150 operates the speaker 140 and inputs themanagement manpower to the death leap attempter.

Due to such a control center, not only is it possible to monitor thedeath leap attempt of the death leap attempter more effectively, but itis also possible to prevent the death leap of the death leap attemptereffectively.

The spiked unit 160 forms a plurality of cutting edges along alongitudinal direction. As shown in FIG. 16, the spiked unit 160 isdetachably installed in an installation groove formed in any one or moreof the aforementioned supporter 110 and the rotator 120 by sliding on adirection of arrow.

Due to the aforementioned spiked unit 160, the death leap attempter isprevented from grasping the supporter 110 or the rotator 120 from thefirst place, and thus the death leap attempt of the death leap attemptercan be inhibited more effectively.

Therefore, according to the falling and death leap defense cylindersystem according to the first embodiment of the present disclosure 100that includes the supporter 110, the rotator 120, the surveillancecamera 130, the speaker 140, the control center 150 and the spiked unit160, due to the spiked unit 160 detachably installed in the supporter110 or the rotator 120, the falling and death leap of the death leapattempter can be inhibited more effectively, and there is an effect ofinstalling the combining unit in the structure without damaging thestructure.

Further, according to the falling and death leap defense rotatingcylinder system according to the first embodiment of the presentdisclosure 100, when the death leap attempter attempts the death leap,the center of gravity is disturbed, and thus the death leap of the deathleap attempter can be inhibited effectively, and there is an effect ofpreventing a person other than the death leap attempter from falling.That is, in areas with high risk of falling, there is an effect ofpreventing safety accidents of children or adults and the like fromfalling due to negligence.

Hereinafter, with reference to the attached drawings, a falling anddeath leap defense rotating cylinder system according to the secondembodiment of the present disclosure will be explained in detail.

The falling and death leap defense rotating cylinder system according tothe second embodiment of the present disclosure 200 includes thesupporter 110, the rotator 120, the surveillance camera 130, the speaker140, the control center 150, a plate unit 260, a connecter 270 and alighting 280.

Here, the supporter 110, the rotator 120, the surveillance camera 130,the speaker 140 and the control center 150 are the same as thoseexplained in the falling and death leap defense rotating cylinder systemaccording to the first embodiment of the present disclosure 100, andthus repeated explanation will be omitted.
